Ensure that the glass, setting blocks, and snap in glazing bead have
been installed according to the instructions in figures 69 and 70 on
page 40. Begin by measuring the DLO width and height. Cut the
exterior glazing gasket to length by using the following formula.
STEP 7) EXTERIOR GLAZING GASKET INSTALLATION
EXTERIOR GASKET LENGTH = DLO DIM. X 1.02 or (DLO DIM. + 2%)
SEAL 1" VERTICALLY AND HORIZONTALLY IN THE GASKET RACE WITH
BUTYL TYPE SEALANT AT ALL CORNERS. SEAL THE ENDS OF THE
HORIZONTAL GASKETS TO THE VERTICAL GASKETS. CLEAN OFF ANY
EXCESS SEALANT.
To install the exterior gasket, start by pushing the precut gasket in
place at the ends. Move to the middle, then to 1/4 points and work the
"waves" toward the ends. Try to maintain 8" to 12" placement of the
gasket to ease the installation.
